[DRBD-user] drbdadm verify issues

[Joshua West]

Hey all,

I'm attempting to run "drbdadm verify all" with either 8.3.0 or 8.3.2
and having no luck.  In fact, upon executing that command and waiting a
bit, I still see no progress made in /proc/drbd (0% for all resources). 
Additionally, dmesg starts to receive logs like:

drbd0: [drbd0_worker/24497] sock_sendmsg time expired, ko = 4294967204
drbd2: [drbd2_worker/25816] sock_sendmsg time expired, ko = 4294967203
drbd1: [drbd1_worker/28768] sock_sendmsg time expired, ko = 4294967203
drbd0: [drbd0_worker/24497] sock_sendmsg time expired, ko = 4294967203
drbd2: [drbd2_worker/25816] sock_sendmsg time expired, ko = 4294967202
drbd1: [drbd1_worker/28768] sock_sendmsg time expired, ko = 4294967202

and just keeps on going.  'dmesg' output on the peer drbd server looks
similar.  All drbdadm commands -- on both servers -- freeze at this
point, but rebooting just one of the two systems resolves the issue.

For reference, my /etc/drbd.conf looks like:

global {
    usage-count no;
}

common {
    protocol C;
    syncer {
        rate 1G;
        verify-alg sha1;
    }
        net {
                 allow-two-primaries;
        }
    startup {
                become-primary-on both;
        }
}

resource vm_ha-test1 {
        on xen-ha-f1.unet.brandeis.edu {
                device    /dev/drbd0;
                disk      /dev/vg0/drbd-vm_ha-test1;
                address   129.64.101.47:7789;
                meta-disk internal;
        }
        on xen-ha-g1.unet.brandeis.edu {
                device    /dev/drbd0;
                disk      /dev/vg0/drbd-vm_ha-test1;
                address   129.64.101.49:7789;
                meta-disk internal;
        }
}

resource vm_ha-test1_swap {
        on xen-ha-f1.unet.brandeis.edu {
                device    /dev/drbd1;
                disk      /dev/vg0/drbd-vm_ha-test1_swap;
                address   129.64.101.47:7790;
                meta-disk internal;
        }
        on xen-ha-g1.unet.brandeis.edu {
                device    /dev/drbd1;
                disk      /dev/vg0/drbd-vm_ha-test1_swap;
                address   129.64.101.49:7790;
                meta-disk internal;
        }
}

Any help would be greatly appreciated, as I'd prefer to have nightly
cron jobs verifying the state of the drbd resources' data.

Thanks.
